Defoliated 4 big fan leaves off each plant on 12-30-23 for more light penetration to the lower stems

Had an issue. Wasn’t sure what it was. Finally my PH pen came in the mail my RO water is 10.5 NOT GOOD! Ph down to 5.9 and did a heavy water. Hopefully they recover quickly.

Cut 2-3 big fan leaves off from each plant. ph @ 6.2 and gave each 1L. I also added bloom on 12-31 after not seeing a difference in the brown spots going away. after feeding with big bud brown spots were gone. deprived of potassium and phosphate.
